Professional Liability Insurance Guide
Professional liability (Errors & Omissions) insurance protects consultants, agencies, and service firms from claims of negligence or mistakes.
What professional liability insurance is
Professional liability insurance β also called Errors & Omissions (E&O) β covers claims arising from your professional advice, services, or work product. It pays legal defense costs and damages when a client alleges you were negligent or failed to deliver.
Who needs it
Consultants, accountants, financial advisors, marketing agencies, IT service providers, architects, real estate agents, and any professional whose advice materially affects a clientβs outcomes.
How claims-made policies work
Most E&O policies are 'claims-made,' meaning the policy must be active both when the mistake occurred and when the claim is filed. When switching carriers, buy a retroactive date that reaches back to your original coverage.
Cost benchmarks
Independent consultants: $40β$85/month for $1M limits. Design firms: $95β$220/month. IT MSPs: $140β$350/month depending on client concentration and cyber add-ons.
Frequently asked questions
Does E&O cover intentional misconduct?
No. E&O covers negligent acts, errors, or omissions, not fraud or willful wrongdoing.
Do I still need E&O if my contract has a liability cap?
Yes. Clients may still sue for the capped amount, and defense costs alone can exceed the cap. E&O also pays those defense costs.
